IMPROVEMENT IN PUMP ATTACHMENTS.

Specification forming part of Letters Patent N o. 1'27,979, dated May30, 1876; application filed April 21, 1876.

To all whom it may concern:

Be it known that I, S. JARVIS ADAM of the city of Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Pump Attachments; and I do hereby declarethat the following is a full, clear, and exactdescription thereof, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of thisspecification.

My invention relates to that class of pump attachments known as horns,the purpose of which is to afford a support and fulcrum for the lever orpum p-handle and the improvements I have made therein consist in theconstruction of plates provided with recesses or openings for thereception of the pivot of the pump-handle, and holes t'or screws orother form of fastening to the wood trunk of the pump, and curved attheir one extremity, and there fitted with a joint, made permanent bymeans of a rivet or other device, so that, when ready for use, at alltimes the recesses or holes for the reception of the pivot may bedirectly opposite each other, and at right angles with the slot oropening for the reception of the' handle; also, in the construction of apivot,

fitted at its extremities to the recesses provided in the counterpartplates of the horn, and in that portion occupying the wood of thehandle, provided with one or more lateral burs or fins, to the end thatwhen driven into the wood the shrinking ofthe fiber upon it may retainit firmly, and any subsequent shrinkage from it may not interfere withits action with the handle.

In the accompanying drawings, Figure l is a view of the upper portion ofa pump fitted with my improved horn. Fig. 2 is a view of the horndetached from the pump and handle, Fig. 3 is a view the recess shown insection.

of the handle, place.

I construct the two parts 'B B, which may be of cast or stamped metal,and I provide them with the holes Q, for attachment to the showing thepivotor pin in pump stock or trunk by means of screws, and with therecesses A in the flange R, for the opening from the common center 0.

Ordinarily, the hole A is drilled through the plates answering to B andB, and after being put in place the pin D is 'driven through theseopenings and the handle, which is between them. The shrinking of thewood loosens the pin, which then is in danger of being lost." Theplates, too, being put in place independently of each other, arefrequentlyout of line, and the result is the binding of the handle inits slot, or undue wear upon one side.

In my horn, when completed, each part is true within itself. The tworecesses A coming directly opposite each other, the handle W is placedbetween them, and the ends of the pin D drop intothe recesses A. Thewhole is put in place and made fast.

I claim as my invention-- A The herein-described pump attachment,consisting of the two plates B and B, united by the hinge O, andprovided with the recesses A, as and for the purposes shown and setforth.

In testimony thatI claim the foregoing as my own I have afiixed mysignature in presence of two witnesses.

S. JARVIS ADAMS.
